i just picked up a remington 700 300 RUM this morning on a trade. i traded my taurus judge and my lcp 380 for this 300 rum. it has a jewled bolt muzzle break trigger job picatiny mount nikon prostaff BDC 3-9x50 and has only had one box of ammo i think i did pretty damn well in the trade.. anyways i need brass and i cant find any anywhere online or at local shops !i would really like to not buy loaded ammo just to get brass.. also if any of you have a sweet load data for a factory rem 700 26in barrel i would love somewhere to start if i can get bulets... also is this super high BC nessary to shoot 1k ? can i get away with a 180gr with a bc of .5?? ish ? im just getting into long range precision shooting iv shot a longgg way before but with a m2 50 cal ha.

That is a sweet looking rifle. You can easily determine the effective range of the bullet you use by using a ballistic calculator. A .5ish BC will be borderline to 1000 yds at PA elevations, using 1800 fps as a minimum opening velocity. For 180 gr bullets you can expect velocities in the range of 3300-3400 fps.

In order to get the most out of the RUM, use heavier bullets. I plan to use the 230 Berger Hybrids in mine with RL33 as first choice of powder. I'll also be trying 200 gr Cutting Edge Bullets with Retumbo. There are several advantages of going with heavier bullets. Most being in external ballistics of greater BC for greater range and less wind drift. Also more mass and destruction delivered down range as well as slower short range velocities for more controlled expansion and less damage. Also slower burning powders with lower velocities will increase your barrel life. Everything about the bigger bullets is good.

If you want to shoot to 1K, you will probably want to get another scope that you can reliably dial your corrections. I highly recommend the 5.5-22 Nightforce.

If I did not already have the Amax bullets on my shelf, along with a load that I'm very satisfied with, I would be seriously considering the 215grain Berger Hybrid. Alternatively, you could go for the highest BC with the 230grain Berger.

its too bad everything i need for this rifle to get shooting is out of stock... bullets...brass.. even my local reloading shop doesnt carry retumbo or h-1000 which seems to be the two most popular powders

Welcome to LRH

hey thanks alot for all that info ill take it to heart when i open my wallet and start buying componets when they become avaialble again

that is a awesome rifle build you have there .. do you think with my 26in barrel i will have enough length to push such heavy bullets to a acceptable velocity its a factory barrel.

Thank you and yes, I think you will be able to push the heavy bullets just fine with your 26" barrel. Given your short barrel, I would make the 208Amax or the 215grain hybrid my bullets of first choice.

The reason I did not change from the 208amax to the 215 or 230 bergers is because I ran the numbers on expected velocities. Although the 208 had a lower BC, by virtue of going much faster it actually shoots flatter and with equal wind drift out to ~1200 yards. 1200 is further than I would be willing to shoot at a critter. So going with the bergers did not necessarily make sense given that I had a well developed load with the Amax (91grains of Retumbo, lit by Fed215M)

it says the a max is not a good hunting bullet have u killed any game with this bullet i think under 300 yards on a shoulder it might be a bullet failure i mean this is a long range rilfe but **** if that trophy steps out at 50 yards im gunna squeeze... last yr i shot a 14 point with my .270 at 10 yards away haha

its too bad everything i need for this rifle to get shooting is out of stock... bullets...brass.. even my local reloading shop doesnt carry retumbo or h-1000 which seems to be the two most popular powders

You're very welcome, and just keep checking the various suppliers. Bullets, powder and brass should be and are coming back to the online suppliers as well as the shelves.

There is no perfect all range bullet. Some are better at short to mid range and some better at longer ranges. You need to decide what your priorities are. The 200 gr Nosler LRAB may be a good compromise for you, but don't believe the advertised BC. It is closer to the 210 Berger and 208 Amax.
